.0em plus.0ex minus.2ex-.5emCOCO Benchmark. Many existing works on zero-shot detection [1]} and open-vocabulary detection [2]}, [3]}, [4]} benchmark on COCO. This setup divides COCO vocabulary into 48 base categories for training and 17 novel categories for testing. We follow the standard practice and report results in the generalized detection settings without instance segmentation. The main metric is AP50 of novel categories. Similar to LVIS, we report the mean of 5 independent runs to ensure reproducibility.
